The number of electronic federal tax returns filed so far from Tennessee has increased from last year.

The Internal Revenue Service in Atlanta says as of Feb. 29, 1.4 million electronic returns have been filed from Tennessee. IRS spokesman Mark S. Green says taxpayers’ refunds have also increased this year to an average of $3,128.

The IRS expects more than 150 million tax returns to be filed this year.

Because of the Emancipation Day holiday in Washington on Friday, April 15, taxpayers have until April 18 to file and pay any tax due. In Maine and Massachusetts, the deadline is April 19 because of Patriot’s Day observances on April 18.
